After some days of study of mm layer and pdf x86 docs I am going to
writing some code.
The first problem that arise is where to put the virtual address of the
irq stacks. For a lot of reasons I think the best place for the virtual
irq stacks in the fixmap area. Is that the best place to put the irq
stack virtual addresses?
